用2、3、6、9怎么算24点啊

Question

要用两种方法！谢谢！

Answer 1

(2 + 6)/3 * 9=24；2 *6 + 3 + 9=24

2+6=8

8/3=三分之八

8/3*9=8*3=24

2 * 6 + 3 + 9

=12+3+9

=24

扩展资料：

在有解的牌组中，用得最为广泛的是以下六种解法：(我们用a、b、c、d表示牌面上的四个数)

①(a-b)×(c+d) 如(10-4)×(2+2)=24等

②(a+b)÷c×d 如(10+2)÷2×4=24等

③(a-b÷c)×d 如(3-2÷2)×12=24等

④(a+b-c)×d 如(9+5—2)×2=24等

⑤a×b+c—d 如11×3+l—10=24等

⑥(a-b)×c+d 如(4-l)×6+6=24等

需要说明的是：经计算机准确计算，随机的4个1-13的整数(数字可重复)中，能够算得24的概率约为74.835%.

“巧算24点”能极大限度地调动眼、脑、手、口、耳多种感官的协调活动，对于培养我们快捷的心算能力和反应能力很有帮助。

1，2成6加3加9 2，9减3减2成6

Answer 4

9-3=6 6+6=12 12*2=24 2*6=12 3+9=12 12+12=24

Answer 5

(9-2-3)*6
=4*6
=24

asin(3-2)/6+9
=asin(1)/6+9
=90/6+9
=15+9
=24
